After resolving the crystal cluster crisis, Su Yao intensified her training to improve her control over her supernatural abilities. One day, as she was cultivating in the backyard of her safe house, a system alarm suddenly sounded: "A large-scale horde of Fiery Hell Beasts has appeared five kilometers to the southwest and is rapidly approaching!"

Su Yao's eyes sharpened, and she immediately gathered her team. "This beast tide is coming in fiercely, we must protect the safe house." After saying that, she activated the system to investigate. On the screen, a group of Flame Prison Beasts, their bodies engulfed in raging flames and resembling tigers and leopards, were charging towards them. Wherever they passed, the earth was scorched black and lava surged.

Su Yao quickly deployed her team: "Those skilled in defense, line up in front of the safe house and raise earth elemental shields; wind elementalists, disrupt the beast horde's path; fire elementalists, prepare to counterattack with me." Everyone accepted the orders and performed their duties.

The swarm of fiery beasts arrived in an instant, bringing with it a wave of intense heat. Su Yao formed hand seals, and with the power of the crystal clusters, a massive ice wall appeared before the safe house. The fiery beasts crashed into the ice wall; the collision of flames and ice produced a hissing sound, and the ice wall rapidly melted away.

"Concentrate your firepower on the leading Infernal Beast!" Su Yao shouted, an ice blade flashing in her hand as she charged towards the horde of beasts with lightning speed. Behind her, the Fire Elementalist unleashed a river of flames that intertwined with the Infernal Beast's fire.

However, the Fiery Hell Beasts were numerous and had thick hides, so while the team's attacks were effective, they couldn't stop the advance of the beast horde. Seeing this, Su Yao activated the system's "Weakness Insight" function and instantly discovered that the flame cores on the bellies of the Fiery Hell Beasts were relatively vulnerable.

"Attack their bellies!" Su Yao shouted, simultaneously using her spatial abilities to instantly teleport to the underside of a Flame Prison Beast, her ice blade piercing its fiery core. The Flame Prison Beast let out a miserable howl, its massive body crashing to the ground, the flames gradually dying down.

Encouraged by this, the team members attacked even more fiercely. But the Flame Prison Beasts also launched a frenzied counterattack. A huge Flame Prison Beast opened its blood-red maw and spewed out a pillar of fire several meters in diameter, which rushed straight towards the safe house. Su Yao didn't have time to think. She used all her superpowers and, just as the pillar of fire was about to hit the safe house, she used an arc-shaped ice shield to deflect it to the side. However, she herself was also shaken by the aftershock of the fire, causing her blood and qi to surge.

At this moment, Su Yao realized that a swift victory was crucial; otherwise, once her team members' abilities were exhausted, the safe house would inevitably fall. She acted decisively, retrieving several crystal clusters containing powerful energy from her spatial storage, fusing them with her own abilities, raising her hands above her head, and chanting incantations. In an instant, dark clouds gathered in the sky, and icy raindrops mixed with hail poured down, each drop transforming into a sharp ice needle that shot towards the horde of Fiery Hell beasts.

The Fiery Beasts struggled painfully in the rain of icy needles, and the beast tide's offensive gradually slowed. Taking advantage of this opportunity, Su Yao commanded her team to launch a final assault. In an instant, supernatural light shone brightly, and the Fiery Beasts fell to the ground one after another.

After a fierce battle, the beast tide was finally repelled. Su Yao and her team were exhausted, and the safe house was damaged in many places. While arranging for her team to rest, Su Yao used the system and supplies to repair the safe house.

This battle made Su Yao realize that their strength still needed significant improvement. She decided that once the safe house was repaired, they would delve deeper into the mysterious ruins they had discovered earlier. It was said that the ruins held powerful forces and precious treasures, which might help them better survive in this high-temperature apocalypse and protect their loved ones and home.
